PAINT SURFACING AND DISTRIBUTING MACHINE FOR DIPPED SHINGLESl Filed Aug,9, 1927 Patented Mar; v3, 1931 UNITED STATES.

PAINT SUREACING AND DIsTRIBUTI-NG MACHINE EoRIiIPPEDsIIINGnEsI iApplication filed August 9,.;v19`27.jseriaifno. Yaimais;

This invention relates to a machine for distributing and improving thepainted or stained surfaces of shingles immediately afterv dipping. yIts object is to provide :meansl whereby the' surplus paint or stain ondipped shingle may be quickly removed so Ythat the shingles may beimmediately bundled forfshipment without lthe probability of theirbecoming cemented together and consequently injuringl the paintedsurface or 'the shingle it-self.v y

A further object gained bythe device is that the texture of thepainted'slurface is Aevenly maintained and that the dipping medium isforced into the crevices of the shingle which leaves the machineina.practically dry condition.y

With these and other objects in view I arrange my machine to- 'cons'istof two horizontal rolls which revolve slowly in bearings carried bythevertical members of a simple i.

framework, on the top of which is mounted l a motor which drives theaforesaid rolls by worm gear from a chain sprocket wheel over- Y hangingthe end ofthe machine.

The horizontal rolls are cover-ed withl carpet or other like textilefabric and a double row of brushes extends between the side or endframes in front and in a line with the adjacent horizontal peripheriesof the carpeted rolls. n

The brushes may be arranged in sections convenient for removal and areplaced with their bristles opposite so that the shingles may beintroduced between them and thence follow on between the two rolls bywhich they are ydrawn forward through the machine to be deposited upon areceptacle bench for disposal.

peted roll by a second sprocket wheel on the lower '.roll which drives4diagonally to the opposite side of the roll sprocket and thence followsaround an ladjustable and a fixed 'circular' surfaces' are' driven inopposite.v

Alower carpetedl rollcarries onl its extremity driven sprocket wheel lby'the' driving chain `side cam y21 and against the action of the liftedto the operating bench 23'and fed by sprocket tol obtain thel'requireddriving con-r` dition.

One orotherset ofthe'brushes may'receive i i" a slight oscillating o-rend'wisemotion-ifI dey purpose of improving the/tex# ture; of thepainted surface.l f :V if;

YThe inventionis more clearlyl exhibited by .the drawingsfherewithforming part of this f invention and in which Fig; 1l is aside elevationand Fig. 2, an end'elevationigaand*in which .thefdriving motor isindicated by @the` 'worml wheelI spindle 4 carrying-the main vdrivingsprocket lwheel 5', this driving gea-r being carriedy by the topymember@` of the supporting' framework;the` side or endframes'? of whichsupport thefbearingsforthe spindlesv "8 of the' horizontal rolls 9".lThese latter are f covered. with carpetover the whole of theirdirections by aV chain. A double row of brushes lO'extends between thetwo end frames-7 being placedwith their bristles opposite so thattheshi-ngles maybe insertedbetween themQ'They spindle of the i i twoVchain sprocket wheels 1'1 and 12. lThe former Vis in: 'engagement withkthe motor 13y and thelatter rotates the upper cylindrical roll 9 by itssprocket wheel14 bythe drivingj 8 chain 15 which is ke Jtin suitabletension by the fixed idler 16, an the adjustable idler 17, the latter'beingfsupported bythe lever 18, under the influence of the spring 19.

Y When desired for improving the character 8' of the painting work oneof the rows of brushes 10 may be made togive a slight oscillating motionby connection to the cam lever 20 acting inconjunction with therevolving H00 spring 22 which ygives the return motion to the brushcarrier.

An operating bench across the front of the framework is shown at 23 anda receptacle bench upon which the finished shingles are delivered isshown at 24.

The process of operation in connection with this machine is to first dipthe shingles in a paint or stain bath from which they are .m0

manual labour between the horizontally dis posed brushes 10 receivingthereby an even distribution to their coat of paint.

The shingles are thence pushed forward to i v be received by the carpetcovered rolls being thereby drawn through between them and deliveredupon the bench 24 ready for the v bundling operationwithout furtherdelayV or the necessity for other drying operations.

Having now particularly describediny invention lwhat I claim and desireto be protected in by Letters Patent, is:

In a machine of the type'describedl the coin-A bination comprising, aframework, a pair of superposed horizontal rolls carried by said4framework, said rolls having their circulai' vperipheries covered witha carpet-like fabric and being revolved vin opposite directions,

Vtwo vrows of rigidly and oppositely held brushes, said two rows beingin the same vei tical plane and having their horizontal plane ofAcontact in horizontal alignment with the line'formed by the adjacentcylindrical surfaces of said rolls whereby. shingles may be handfedbetween said rows of brushes to be j received therefroinby the acentsaid pair of rolls, a inotor carried by said framework and adapted tooperate said machine through j worm gear and cross shaft, a sprocketwheel on extremity of thespindle of the lower, said roll, acorresponding sprocket wheel on said ci'oss shaft, a Vcha-in engagingsaid sprocket wheels, a second sprocket wheel on said lower rollspindle, a sprocket wheel on the spindle of said upper roll, a fixedidlerrchain wheel, an adjustable idler chain wheel, a chain engag-ingthe last said four wheels and adapted to revolve the upper roll in adirection opposite to that of the lower roll, a cam revolvable on theaxis of and with said adjustable chain wheel, a cam leveroscillatingvand pivotal on a bracket carried by said framework, a con!necting means whereby the oscillation of said lever is utilized tooscillate one row of said brushes against the action of a spring, allsubstantially as described and shown.

In testimony whereof l vaflix my signature.
